I can only wish I doged that bullet!
Nope it hit me but I'm still not sure just how big the damage, I'm getting the impression it was pretty big. There was metal pieces in the sump and fillings in an oil sample. Here's the latest (I really need to put together a full story).
The engine is down and today all going well I will have slid it out and clear. I had to pull the IMSB flange off to see what was in there, below is the hell hole BUT where is the bearing!!! I guess thats the inner race in the tube. Nothing fell out this is what I found after removing the flange.
Any thoughts if its still rebuildable?

You need to fully disassemble the engine to check for excessive wear caused by the IMSB ball bearings on the loose.

Bypro, ok that was what I was thinking but what about the block? How can I check if the bearing turned/spun in the race of the block?

You might call the folks at Flat 6 Innovations and ask their advice on whether to go through the effort of tearing down the engine. They've got lots, if not the most, experience out there.

Once the support bolt/axle breaks the IMS just bounces around. There is no way to know how much damage was caused without inspecting every surface inside the engine. You can get a sneek peak by removing the oilpump housing behind the front engine mount & inspect the 2 gears inside to see if the metal grit got through the pump.
